Isn't there any performance issue when saving serialized attributes every time?
...end
In out app, User model has a serialized attribute friend_ids, which is
the id array of the user''s friends (used to be a friendships table,
but when that table grew to tens of millions of records, we refactored
it to a User''s attribute). The User model in our app is saved very
frenquently, and many users have more than 1 handred friends, so the
friend_ids may has 1kB long. Some of my colleages opposed to use
serialized friend_ids, and suggested to used a comma separated string
instead because saving 1kB each time would have performance issue.

Promise raid cards
Hello.
I would like to know if promise RAID cards are compatible with CentOS / RHEL
?
I have seen that only SATA is supported on the RHEL hardware compatibility
list. The other ATA raid cards seems not to be compatible. They give source
code and promise grants compatibility with RedHat 8 and 9 but not RHEL.
I would like to know if somebody tried a ATA raid card like Fasttrack
TX2000, SX4000,
